Owned my 94 jag for about a year now. Bought it with 63000 miles on it. 70500 now and I am having issues with it. Intermittently shakes when driving. It will be fine for a day and then really bad the next day at all speeds. Engine light is on and code reads Fail Fuel 39.

Took it to my mechanic. He put it on diagnostic and nothing showed up. He balanced and rotated tires took.it for a.test drive and said it road fine. I pick it up and it begins shaking at 30 miles per hour and engine light is back on.

Any advice as to what it could be. Thanks!

My advice... change mechanics!

 

Welcome to the forum rosco59,

Good to have you with us at Jaguar forums.

Interesting your mechanic would think the intermittent shaking was from out of balance wheels! FF39 is a regular and, as you have found, also a frustrating issue. Check this thread:

Welcome.

Other things in my head are:

Trans fluid really OLD, so trans judder is causing some shaking?
Tailshaft centre bearing has a failed rubber mounting, which causes a real bad vibration, and sometimes a banging sound on acceleration.
Engine mounts are just plain OLD, all 3 of them.

Obviously the EGR code has something to with what is there, but we dont have EGR systems down here, so no idea what it would cause the engine to do when it fails.
